## Description

py_framels is a python binding to use [framels](https://github.com/doubleailes/fls) rust lib in python

For documentation about framels: [doc guide](https://doubleailes.github.io/fls/)

The module only support 3 functions at the time.

## Install

`pip install py-framels`

## Usage

### Exemple

```python
import py_framels

print(py_framels.py_basic_listing(["toto.0001.tif","toto.0002.tif"]))
```

Should return

`['toto.****.tif@1-2']`

### Functions

#### py_basic_listing

The function provide a packing of the frame sequences using framls format.

```python
import py_framels

print(py_framels.py_basic_listing(["toto.0001.tif","toto.0002.tif"]))
```

Should return

`['toto.****.tif@1-2']`

#### py_parse_dir

The function list all the files and folders in specific directory and pack them

```python
import py_framels

py_framels.py_parse_dir("./fls/samples/big")
```

Return `['RenderPass_Beauty_1_*****.exr@0-96', 'RenderPass_DiffuseKey_1_*****.exr@0-96', 'RenderPass_Diffuse_1_*****.exr@0-96', 'RenderPass_Id_1_*****.exr@0-96', 'RenderPass_IndDiffuse_1_*****.exr@0-96', 'RenderPass_Ncam_1_*****.exr@0-41,43-96', 'RenderPass_Ncam_1_00042.exr.bkp', 'RenderPass_Occlusion_1_*****.exr@0-73,75-96', 'RenderPass_Occlusion_1_***.exr@74', 'RenderPass_Pcam_1_*****.exr@0-96', 'RenderPass_Reflection_1_*****.exr@0-96', 'RenderPass_SpecularRim_1_*****.exr@0-96', 'RenderPass_Specular_1_*****.exr@0-96']`

#### py_recursive_dir

```python
import py_framels

py_framels.py_recursive_dir("./fls/samples")

```

Return `['RenderPass_Beauty_1_*****.exr@0-96', 'RenderPass_DiffuseKey_1_*****.exr@0-96', 'RenderPass_Diffuse_1_*****.exr@0-96', 'RenderPass_Id_1_*****.exr@0-96', 'RenderPass_IndDiffuse_1_*****.exr@0-96', 'RenderPass_Ncam_1_*****.exr@0-41,43-96', 'RenderPass_Ncam_1_00042.exr.bkp', 'RenderPass_Occlusion_1_*****.exr@0-73,75-96', 'RenderPass_Occlusion_1_***.exr@74', 'RenderPass_Pcam_1_*****.exr@0-96', 'RenderPass_Reflection_1_*****.exr@0-96', 'RenderPass_SpecularRim_1_*****.exr@0-96', 'RenderPass_Specular_1_*****.exr@0-96', 'aaa.***.tif@1-5', 'big', 'foo_bar.exr', 'mega', 'response_1689510067951.json', 'samples', 'small']`

## Benchmark

This is benchmarks of the python binding py-framels vs pyseq at diffirent level of inputs.
Time is always in seconds.

|------------|--------|--------|--------|--------|
| py_framels |0.002173|0.015975|0.359272|0.420266|
|    pyseq   |0.005592|0.060121|2.632283|3.918997|

Note: there is an acceleration at the level of 20000 paths, this is due to the fact
framels is multi-threaded at a threshold of 100000 paths and the bench simulate
5 aovs ( 5 x 20 000 = 100 000 paths ).
